WITNESSES:

(I x BY ATT0RNEYs intothe cylinder, purifying, washing and compressing a separate portion of the products of. combustion without addition of oxygen, and injecting a liquid fuel intothe tor is placed under Conditions for favorable working. If the gases intended to be mixed with oxygen are not to be purified or cooled, they can be left in the motor cylinders, only the necessary amount'of' gas being allowed to escape to inject the fuel. The oxygen intended to form the explosive mixture is then injected directly into the cylinders.

' marines and submersible boats.

What I claim is 1'. A process for supplying fuel to heat engines working on a closed cycle and in -which the fuel is injected into an oxygencontaining gas or firing mixture within the cylinder, Whl Qh consists in charging a portion of the products of combustion with oxygen, and admitting the portion so oha rged eeaese cylinder by means of said separate compressed portion.

2. A process for supplying fuel to heat engines Working on a closed cycle, and in which the fuel is injected into an oxygencontaining gas or firing mixture within the cylinder, which consists iii injecting oxygen into one portion of the gases resulting from combustion to form a supporter of combustion, purifying another portion of the products of combustion, and injecting a liquid fuel into the cylinder by means of said purified portion. I I

3. A process of operating heat engines on a closed cycle which consists in cooling and purifying the gases resulting from combustion, charging a portion ofthe cooled and purified gases with oxygen to form a supporter of combustion and returning the said charged portion to the combustion chamber, compressing a separate portion of the cooled and purified gases, and injecting a liquid fuel into the combustion chamber by means of said separate compressed portion.
